利用我国三大经济区中六个省份的出口和GDP变量,检验出口是否促进经济增长以及经济增长是否带动出口。透过单根检验、协整检验、Granger因果关系检验,发现各经济区不同省份出口和经济增长之间存在着较为复杂的因果关系。为增强出口和经济增长的相互促进作用,要充分发挥人力资本的作用,优化产品结构,并建立相应的配套制度。
Using the export and GDP variables of six provinces in the three major economic zones of our country, we can test whether exports promote economic growth and whether economic growth drives exports. Through single root test, co-integration test and Granger causality test, it is found that there is a complicated causality between export and economic growth in different provinces in all economic zones. In order to enhance the mutual promotion of exports and economic growth, it is necessary to give full play to the role of human capital, optimize the product mix and establish a corresponding supporting system.
